Subject RE: [DISCUSS] Dedicated Resources: Dedicate Pods, Clusters, Hosts to a domain

how do you handle PS if dedicating a host to domain?
If CS supports some kinds of EBS later, EBS can be a PS and shared by multiple cluster, how
do you handle EBS PS ?

Can admin dedicate multiple resources( for example, cluster) to a domain?


If a pod is dedicated to a domain, can another pod be dedicated to a sub-domain of this domain?
If yes, does that mean this sub-domain own two pods?
